Ok I have a new Server I setup and moved my ecommerce store to. It is running cs cart. Its a Linode 6cpu 16GB so should be very fast. I installed LAMP and am running Php fpm 7.3.x
I keep getting gateway errors on the store and it is much slower than the site was on the old server, and it really should be very fast because the site does not have high user base.
Due to the site selling digital products and having sometimes 2GB files uploaded the memory limit and max file upload size is set high enough to allow this . But it was the same on the old server with no issues.
I also installed redis cache but it I cant get it connected to my cscart sites (dev and live site) for some reason so they are not using it.
I need an EXPERT unix centos 8 expert who can find the issue(s) and get the server running fast like it should be.
This is an urgent job. You must have more than 10 server admin job feedbacks.
